XY motor mount v2 - X5S

Here is an example of XY motor mounts made of aluminium.
Used several types of printed mounts but all of them have same problem - become flexible if temp gets higher - i.e. printing within box/enclosure or if motor gets hot when cooling fan fails.
Decided to try aluminium - it is not very hard to manufacture and looks good.
Used standard XY mount as pattern with little extension for corner.
Alu plate is 3mm thick.
Used tools - jigsaw,accu drill, vice and hammer to bend, grinder to clean re
